Each pre-class Podia question is based on the pre-class material and working through the pre-class material will help you formulate your response. Consider the problem and write down/draw out your solution in your class notebook. These questions are designed to hone your skills so that you can analyze and solve mastery problems you will encounter throughout the course.
Two days before the next whole-class session, the pre-class Podia question will become visible in Podia, where you can click on the prompt and submit your answer.
Submissions for pre-class Podia activities are due 1 hour before the start of your whole-class. Be sure to submit your response before the due time.
Day 19 Pre-Class Podia Activity
The formation of molecular O2 in Earth’s atmosphere is affected by UV radiation that breaks these molecules apart: O2 (g) ⇌ 2 O(g)
(a) Express the equilibrium constant K for this reaction.
Results from experiments carried out using different initial pressures of O2(g) at a high constant temperature T are shown in the images below.
(b) Estimate the value of K for these two systems and compare your results.
(c) Discuss whether the value of K depends on the initial pressure of O2(g) and O(g) in any given system.
